To all whom it may concern:

Be it known that I, DAVID J. JENNINGS,

a citizen of. the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Automatic Ma- Ill chines for the Manufacture of Paper Receptacles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the artto which it pertains to make and use the same.

This invention relates to machines for the manufacture of bodies for paper receptacles and has special reference to that type of machine which will make bodies for paper receptacles similar to the type shown in my U. S. Letters Patent No. 890,985, dated June 16, 1908, and also for the manufacture of the bodies of the pa er receptacles as shown in my U. S. app ication Serial Number 852,635, filed July 23rd,-1914.

The object of this invention is to produce a machine which will automatically roll up, paste and deliver a body of a paper receptacle.

Another object of this invention is to combine a multiplicity of independently oper ated machines into a single operated machine so that a number of bodies for paper receptacles may be made simultaneously.

A further object of this invention is to simplify the construction of the machine for the manufacture of paper receptacles shown in my U. S. Letters Patent Number 1,107,956 of August 18, 1914:.

Other objects of this invention will ap pear in the specification hereinafter.

This invention consists in providing a series of individual mandrels for rolling up blank sheets of paper into bodies of receptacles.

The invention further consists in providing a machine which employs vacuum means for the manipulation of the paper sheets prior to and during the process of rolling said sheets into the bodies of receptacles.

This invention further consists in providing a series of sliding valves and sliding valve mechanisms whereby certain conduits in the machine will have alternate communication with vacuum producing means and the open air.

In the drawings, Figure I, is a top plan view'of my invention showing the location of the several mandrels and their respective Specification of LettersPatent.

In constructing this machine I will employ a series of body making machines, each body making machine bein similar to the machine described in my atent Number 1,107,956. Revolubly mounted within the base 1 is a shaft 2 which is provided with a hollow portion 3, which hollow portion 3 terminates at its lower end in the conduit 4. The upper end of the hollow portion '3 has permanent communication. with the hollow portion 5 in each of the arms 6. As will be seen by referring to Figs. I and II, I prefer to form the arms 6, 6, 6, 6, in one piece and securely fastened to the revoluble shaft 2 by any suitable means such as a set screw 7 and have so adjusted the arms that the hollow portions 5, 5, 5, 5, and the hollow at all times communicate with Conveniently located on shaft 2 it provide beveled gear plate 8 hav ing suitable teeth 9 which are adapted to he engaged by the teeth 10 or the intermittent gear 1L said gear 11 being driven by proper power applied to the shaft'lQ mounted in th hearing 13. EV hen the shaft 12 is revolved the gear 8 is accordingly revolved hich in turn controls the movement oithe she and the arms 6, 8 =6, 6. or each arm 6, i provide combined centric'and eccentric holt (see Fig, l upon the concentric portion 16 oicwhich is hinged the hearing 15. On the ecce' portion 1? of said bolt ll l hinge th 18 of the collar 1% by passing portion 17 through the orifice flange 18. At the inner end of the he l have mounted the central portion 22 the mandrel, which porti n revolves on said bearing 15 between the shoulder :23 and J3 Ll the flange 2% i one SCTBW On the central '4 liOVlClG dove portion 22 of the mandrel iounted the t tails :26 26, upon which are rportions 27 2? which complete e contour of the mandrel. At the end of each portion 2?,aiid Qfilprovide an extension and 29 which extension is provided With inwardly extending flange 28, and 28, each of which ere adapted to eno'aoe With and he ret 'ned in thepgroove of the collar 19, {see i IV and 1X). The hearing 15 is provided with hollow portion 30 which is provided with auxiliary conduits 31, 31, 31, 31, which in turn terminate at the outer surface or the reduced portion 3? of the bearing; 15. The hollow portion 30 has communication with the conduit 33 which in turn is adapted to communicate With the hollow portion 5 of the arm 6 through the medium of the l lQXl" hle tube 3% and th conduit 35. In the central portion 22 of the mandrel i provide openingj o which communicates with the reduced portions 3? thus a direct communication between the outer periphery the roandrel and the conduit l is at all times provided.

The upper portion the base 1 is formed into ;an enlarged head which is provided with projections 38, 38, 38, 38, which are formed hollow as at 39, 39, 39, 39; said holvloiv portions having communication with the hollow portion ll) which in turn has e d ect communication .With the conduit il leading to a vacuum producing rneens such es a pump or other Well liIlOWK} vacuum producing mechanism, not shown.

becureiy nioun ed to the central portion 22 have provided a e8 out out as l9 to allovv' the auges 28, 28 or the extensions 29, 29 to engage with the groove ot-the collar 19. When the 18 ca ried forward-(in direction indicated of the errow in Fig l) the gear in he teeth or the raclr 50 revolving the rnendrel. desi red to form the bodies of the receptacle a lolanlt oi paper 51 is placed on the die plate in the manner hereinafter et forth, The mandrel losing brought forward through the action or the orin 6 rolls from the portion 52 of the reel; and as it raises itseli up to the surfacev of the die pla e the space 39 thus allowing the vacuum to draw said sheet or paper 51 against the outer surface of the mandrel The suction cause by the vacuum holds said sheet 51 agziinst said mandrel more than one revoluti n soid'roandrel has been completed which the conduit 4 communicetes with the space 48 and allows the en trance of eir and shuts oil the suction caused y the vacuum hence the engagement hetvveen the caused by the vacuum is rel-eased.

Wheel 4-8 en cges thus l ocated'as to precede the mandrel and is kept rrorn n aging' vitn the surface oithe die plate 45 by means oi a spring 5 1- Which tends to lreep the paste her 53 and the supporting arm 55 suspended. The posts loci: 53 is carried by the rod 55 which in turnis carried by the supporting arm 55. To the inner end of the rod 56 is sit" ached a roller 57 which isadapted to he by the inclined strip 58 in such it manner that otter one revolution of the mandrel has heen com-- pleted the paste loox53 is brought downward thus allowing the roller 59 to engage the remain portion or the paper the some "-77 ii on ad in order to positively 1 ill gear Wheel the conduit 4- coininunicates With a paper blank 51 and the mandrel V 1 1 poster cor; o3 pivotally mounted to the arm 6 is so tached thereto and engages with the rack 50 while the roller 57 is engaged by the inclined strip 58. The mandrel is advanced from one end of said die'plate to the other i er the receptacle thus formed. After a predetermined pause, caused by the absence of the few teeth in the intermittent gear 11 the arm 6 is again advanced thus further advancing the mandrel. As the gear wheel 48 travels over the portion 52 of the rack the mandrel being beyond the surface of the die plate 45. swings downwardly; the central portion 22 thereof hinged on the concentric portion 16 of the .bolt 14-allows said portion 22 to swing on a perfect arc, the extent of. the swinging being governed by the curve of the portion 52 of the rack 50. The dove tailed portions 27,27, of the mandrel being connected as hereinbefore set forth to the collar 19 and the flange 18 are adaptedto be forced downward in an arc beyond the are 1 of the central portion 22 thus diminishing the circumference of said mandrel as a whole and allowing the completed body portion of a receptacle to fall from said mandrel. Upon the further movement of the arm 6 and the hereinabove mentioned mandrel the dove tailed portions 27-, 27, are returned to their original position and form the mandrel back mtoits normal contour ready for the rolling of another body of a receptacle on thenext die plate 45. In order to provide a bearing for the inner end of the mandrel I have provided a lug 61 which engagesin the portion 62 of the depending arm 63.

. From the above it will be seen that I have described the operation of this machine as far as the manufacturing or forming of the 1 body of a receptacle is concerned. Ii will now describe the operation and mechanism for automatically feeding. the paper blanks .51 to the die plate 45, which is as follows:

will act upon their respective lugs 66 on theinner end of the pivotally mounted arm 67 thus causing the outer end of the arm 67 to travel upward and carry therewith the tube 68., The arm 67 is pivotally mounted tov the standard 86 as at 85. The lower end of the tube 68 is provided with a lug 69-to which is pivotally, mounted-a link 70 whibh in turn is pivotally 'mounted to theexf treme outer end of the arm 67. The upper end of said tube 68 is provided with a fiexi-.

ble air impervious tip 71 {preferably flared as shown in Fig. II.- The die plate 45 is provided with a countersunk orifice 72 through which passes the tube 68, and in which rests the tip71 so that said tip 71 is level with or below the surface'of the die plate 45, The tube 68 is provided with a hollow portion 7 3 which communicates with the tip 71 and which also communicates with an elongated orifice 74 in the side of the tube 68. On the under side of the die plate 45 I have mounted a hollow projection,

75 in'which the tube 68 operates. I provide an elongated orifice 76 on one side of said projection 75 in which the lug 69 travels. Approximately in line with or a little above the lower extremity of the hollow portion 73 of the tube 68 I provide an orifice 98 in the projection 7 5" which orifice 98 is adapted to communicate with the elongated orifice 74 in saidtube 68 at predetermined times. At a point above the elon ated orifice 74 I provide in the projection 5 an orifice 77 which communicates with a conduit 88 leading to a suitable vacuum producing medium, not shown. -When the arm 67 is carried upward as hereinbefore mentioned the portion 99 of the tube 68 passes beyond the orifice 98 thus preventing the entrance of air'into said tube 68. At approximately the same time the elongated orifice 74 is" brought into communication with. the orifice 77 which leads tothe vacuum producing medium thus causing a suction to be created through the tube 68 and tip 71 This suction continues as the tube 68 travels upward. When the tube 68 travels far enough to allow the tip 71 to reach thelowest sheet 78 in the magazine 79 the lug 65 of the plate 64 passes over the lug 66 of the'arm 67 thus allowing the tube 68 to drop to its original 'normalposition. The suction throu h the tube 68 and the tip 71 causes the owest' sheet 78 to adhere to said tip 71 and thus the tube 68 coming back to j its original position carries with it a blank sheet of paper 78 which takes theplace of the sheet 51 on the die plate 45. In practice two tubes 68 and their co-acting parts may be employed for each die plate instead of one as shown, I having shown but one for the purpose of clearness. .The magazine 79 is mounted to'a standardSO and is formed of such contour as to allow the blank sheets 81 to fit snugly therein. At each end of the magazine 79, the bottom of which is 0 en, I provide a ledge 82 and in the midd e of the outer wall of the magazine 7 9 I will provide a small lug 83 the ledges-82 and the lugfl83 being employed to support the blank sheets 81 within the magazine 79. 1 also provide a weight 84 which fits loosely within the magazine 79 and tends to keep ieve sueeessivei to the outside i 3.
